Research progress in Gasdermin family proteins and their association with diseases / 中华微生物学和免疫学杂志

Gasdermin family (GSDMs), consisting of six proteins (GSDMA, GSDMB, GSDMC, GSDMD, GSDME and DFNB59) in humans and ten proteins (GSDMA1-3, GSDMC1-4, GSDMD, GSDME and DFNB59) in mice, might be involved in multiple physiological and pathological processes, including epithelial cell development, apoptosis, inflammation, carcinogenesis and immune-related diseases. Recent studies confirmed GSDMD, which containing an N-terminal domain with pore-forming activity and a C-terminal domain with structural autoinhibition, as a crucial substrate of inflammatory caspases in pyroptosis, pioneering a new area for structural and functional research on Gasdermin family proteins. This review will summarize the latest progress in the structures, functions and association with diseases of several Gasdermin family proteins.

Gasdermin D:The killer protein performs cell pyroptosis / 医学研究生学报

Pyroptosis is a novel programmed cell death mode mediated by inflammatory Caspase,which has a proinflammatory effect and is accompanied by cell membrane rupture and disintegration.In recent years,researchers found that the substrate of inflam-matory Caspase-Gasdermin D(GSDMD)protein,is the key"killer protein"to execute cell pyroptosis.The inflammatory Caspase spe-cifically cleaves the GSDMD protein,forming the N-terminal domain and the C-terminal domain,and eventually results in cell pyropto-sis by protein pores formation.This article focuses on the research progress of cell pyroptosis,the structural features of GSDMD protein, and the mechanism of GSDMD protein participating in the pyroptosis and the disease models.
